4H1713052 Volkswagen ACT. UNIT

This little thing basically translates electrical signals into mechanical movement inside your gearbox. It gets instructions from your car's computer and physically moves parts – things like shift forks or selector rods – to get you into the right gear. It’s not creating the power, it's just controlling how that power gets delivered. Think of it like the muscles that move your hand when you tell it to grab something – the brain sends the signal, but the muscles do the work. It’s a key part of the automated shifting process in modern transmissions. So it's really important in vehicles with automatic or automated manual transmissions. It might control things like how smoothly the transmission shifts, or even if it shifts at all. Different vehicles use them for different things within the gearbox, like selecting gears, controlling clutch engagement, or adjusting transmission fluid flow. If this unit fails, you’ll notice if your car struggles to shift gears, shifts erratically, or gets stuck in one gear. Sometimes it can even put the transmission into a limp mode to protect itself. That’s not something you want happening. A failing actuator can cause really expensive transmission damage if left alone. You can find these pretty easily at places like Fixparts Online, and replacing it yourself can save a bunch of money compared to a full transmission rebuild. It's a relatively small part that acts like a shield for a much larger, more expensive system. Premium parts, premium warranty: Actuator Unit (MPN 4H1713052) has a 12-month guarantee!
